Hopefully Uncle can help. In the mean time, what are your plugs telling you about your combustion?

My HAC valve was the issue. Disconnected lower hose and plugged it. Goes to due diaphragm on distributor. Distributor dizzy has vacuum. So I am now looking for HAC valve that works properly.

Mine can't accelerate hard with the choke in the middle. Is this the case for yours?

Adjust excekerator pump or its leaking
